Remote web based services provide new scenarios in the emerging computing world. File access has been easy after the distributed computing scenario came into limelight. But security for the Distributed file system has been a very crucial problem to take into account. We propose a Cloud based File Management System[CFMS], so as to provide Data services in the cloud along with required security in the form of Intrusion Tolerance. We use the Model View Controller architecture, separating the business layer from the other layers thereby increasing the security of the system. Intrusion Tolerance is maintained by providing hash values and storing them in the controller, which is located separately from the cluster. These hash codes provide the required information on the attacks performed on a file, which when increases is introduced to the manual administrator of the system, thereby permitting him to increase the security still further. Load balancing and replication transparency are maintained in the system for efficient access to the files contained in the system.
